Ether.fi is a decentralized and non-custodial platform that allows Ethereum stakers to earn rewards by locking their cryptocurrency to validate the blockchain network. It enables stakers to retain control of their keys while delegating the staking process to node operators. Additionally, Ether.fi grants stakers an NFT representation for each validator they delegate to. The platform has a sustainable revenue model and prioritizes user custody and composability. Founded in 2022 and based in the Cayman Islands, Ether.fi is the only liquid staking protocol that allows stakers to maintain control over their keys while earning rewards.
